1) Why is my concentrate not draining and my filter clogging?
It is very important when adding water to the coffee grounds to be careful not to stir. When you stir the brew it will disturb the filter bed and the fine sediment will go down and clog the filter. Using a course to medium ground coffee is essential to produce a filter bed that keeps the sediment from falling down and clogging the filter. If you have to use a finer ground coffee, add 2 cups of water in the bottom of the brewing container before you add the coffee. After adding the ground coffee, slowly pour in 5 cups of water. Wait 5 minutes and add the remainder 2 cups of water. Do not stir the mixture and allow it to sit overnight. In the event that the concentrate does not drain entirely out, take a long teaspoon and stick it through the wet grounds and slightly scrap the top of the filter. This should allow you to recover some of the trapped concentrate. Worst case, pour remaining wet grounds through a strainer into another container and rinse your filter. Place the rinsed filter back into the brewing container and add the strained concentrate back into the brewing container.

2) Why is my brewing container leaking?
Examine the outside of the hole in the brewing container (where the cork is inserted). When a knife is used to push out the filter it will damage the brewing container. This will cause a small slice on the side of the hole, which will allow the concentrate to leak past the cork. When pushing out the filter use something round like a straw or an ice pick. If the hole is slightly cut, you can drill a hole slightly bigger than the manufacture hole. 

3) What ground coffee do I use in my Toddy?
Course to medium ground coffee is essential to achieve maximum filtration. Perk is ideal where drip is typically to fine. Fine ground coffee has a larger percent of coffee dust, which will clog your filter. Make sure when you add the water you do not stir with a spoon. Just slowly add the water.

4) How long do I brew my concentrate?
We have found that brewing for 12 hours will give you maximum strength, while producing a less acid cup of coffee. Cold brewing for 12 hours will produce a cup of coffee that has 2/3 less acid than a hot brewed cup of coffee. If you brew longer it will produce a stronger concentrate, but it will also increase the acidity.

5) How long will my concentrates last in the refrigerator?
From day one to day 10 you will not notice a difference in the quality of the cup of coffee. After 10 days, the concentrate begins to deteriorate producing a cup of coffee that slightly stale tasting. If you do not find the taste objectionable, you can keep the concentrate in your refrigerator for 3 weeks. Discard the concentrate after 3 weeks. If you do not drink a pound of coffee in 10 days, you can freeze half of your concentrate and defrost it when you need it. Frozen concentrate will remain fresh tasting for 6 months.

6) How do I brew ½ lb of coffee?
When brewing a half-pound of coffee, first add 1 cup of water in the bottom of the brewing container. Then add ½ pound of medium to course ground coffee. Slowly pour 2 ½ cups of water over the grounds. Finally, wait 5 minutes and slowly add 1 ½ cups of water. Do not stir and allow sitting for 12 hours before draining.

7) How long can I use my Toddy filter?
After brewing your coffee, rinse out your filter with water (no soap). Immediately, place your filter in the refrigerator in a zip lock bag or plastic container. You can use your filter up to 10 times, but discard it after 3 months.

8) How much Acids, and Caffeine does using the Toddy reduce?
Hot brewed coffee has 3 to 4 times more acid than the same coffee brewed in a Toddy. Brewing with the Toddy also produces a cup of coffee that has approximately 2/3 the caffeine of hot brewed coffee.

9) How do I make a Tea Concentrate in my Toddy?
Add ½ pound of your favorite tea leaves in your brewing container. Fill with cold water 1" from the top of the brewing container. Let set for 12 hours and then drain. Store concentrate in the refrigerator. To make a glass of iced tea, add 2 ounces of tea concentrate to 14 ounces of water. Adjust the strength to fit your taste.
